Description

[Technical Field]

[0001] The present invention relates to innerwear to be worn inside an air-conditioning garment equipped with a fan. [Background technology]

[0002] Air-conditioning clothing equipped with fans has rapidly become popular from the perspective of preventing heatstroke, etc. Air-conditioning clothing typically has fans attached to the left and right sides of the wearer's back near the waist. When the fans are driven, outside air is drawn into the air-conditioning clothing. The drawn-in air flows between the wearer's body and the air-conditioning clothing, and then is discharged from the collar, cuffs, etc. In this way, by generating an air flow inside the air-conditioning clothing, the sweat emitted from the wearer's body can be converted into water vapor and discharged to the outside of the air-conditioning clothing. This allows the wearer's body to be cooled effectively.

[0003] At work sites where air-conditioned clothing is worn, workers may also wear a full-body harness over the air-conditioned clothing. A typical full-body harness includes a pair of shoulder belts 52 draped over the wearer's shoulders, a waist belt 55 wrapped around the wearer's waist, and a pair of thigh belts 56 wrapped around the wearer's thighs, as shown in FIG. 9 of Patent Document 1. The pair of shoulder belts 52 typically cross over the wearer's back near the shoulder blades, as shown in FIG. 10 of the same document. The crossing point is passed through a D-ring 58. One end of a lanyard 60 is attached to the D-ring 58. The other end of the lanyard 60 can be secured to a sturdy structure or other structure to prevent the wearer from falling.

[0004] However, when this type of full-body harness-type fall arrest device is worn on the outside of the air-conditioned clothing, the tightness of the full-body harness-type fall arrest device hinders the flow of air inside the air-conditioned clothing, making it difficult to achieve the cooling effect of the air-conditioned clothing.

[0005] In this regard, Patent Document 2 describes a garment 1 with a blower (air-conditioned garment) designed to be fitted with a full harness-type fall arrest device on the outside. As shown in Figure 4 and other figures in the document, this garment 1 with a blower includes a pair of blowers 10, 10 provided on both the left and right sides of the lower back body 3, and inner pads 20, 20 provided on the inside of the back body 3 (towards the back of the wearer) and having breathable and cushioning properties. The presence of these inner pads 20, 20 is said to enable air blown in by the blowers 10, 10 to circulate within the garment 1 even when a full harness-type fall arrest device is fitted on the outside of the garment 1 with a blower. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2020-059944 [Patent Document 2] Patent Publication No. 2021-059798 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the blower-equipped garment 1 of Patent Document 2 may be uncomfortable to wear. This is because, while air-conditioning garments are generally manufactured so that the back body is slightly loose relative to the wearer's back in order to allow a sufficient amount of air to circulate inside the garment, the blower-equipped garment 1, which has inner padding 20·20 on the back body, may cause the inner padding 20·20 to move relative to the wearer's back, which may cause discomfort to the wearer. Furthermore, depending on the wearer's body shape, the inner padding 20·20 may not fit well to the wearer's back (may not be in the right place), which may also cause discomfort to the wearer.

[0008] The present invention has been made to solve the above-mentioned problems, and provides innerwear for air-conditioned clothing that not only ensures space between the wearer's back and the air-conditioned clothing even when a full-body harness-type fall arrest device is attached to the outside of the air-conditioned clothing, but also does not cause discomfort to the wearer. [Means for solving the problem]

[0009] The above issues are: An innerwear to be worn inside an air-conditioning garment equipped with a fan, A front body to cover the wearer's chest, A back body to cover the wearer's back, a pair of left and right rear spacers provided at a distance from each other at approximately the middle of the rear body in the left-right direction; By providing It is possible to secure space between the wearer's back and the air-conditioning garment, The gap between the pair of left and right rear spacers serves as an air flow path for air to pass in the vertical direction. Innerwear This is solved by providing

[0010] In the present invention, a rear spacer is provided on the rear body of innerwear to be worn inside the air-conditioning garment. This makes it easier to fit the rear spacer to the wearer's back (the rear spacer can be made less likely to move relative to the wearer's back) than when an inner pad or the like is provided inside the air-conditioning garment. This ensures a space between the wearer's back and the air-conditioning garment without causing discomfort to the wearer, making it less likely that the flow of air inside the air-conditioning garment will be obstructed.

[0011] In addition, in the present invention, a pair of rear spacers are provided spaced apart from each other in the approximately lateral center of the back body, and the gap between the pair of rear spacers serves as an air passage for vertical airflow. This allows air to flow effectively around the spine of the back, an area of the human body where sweating is particularly likely to occur, and efficiently evaporates the wearer's sweat, thereby effectively cooling the wearer's body.

[0012] In the innerwear described above, the pair of left and right rear spacers are preferably formed from closed-cell foam. Closed-cell foam is generally resistant to crushing under pressure and easily recovers even after being slightly crushed. By forming the rear spacers from closed-cell foam, the rear spacers can be made lighter and less likely to be crushed when pressure is applied, such as when a full harness is tightened.

[0013] In the above-described innerwear, it is preferable that the rear body has a reinforced region reinforced by a reinforcing member, and that the pair of left and right rear spacers are provided so as to overlap the reinforced region. This prevents the pair of left and right rear spacers from approaching each other due to tightening of the full-body harness when the full-body harness is worn, thereby making it less likely that the wearer's back will be pinched between the pair of left and right rear spacers. It also makes it less likely that the air flow path formed between the pair of left and right rear spacers will be crushed. In this case, the specific form of the reinforcing member is not particularly limited. However, if the reinforcing member is too heavy or too hard, it may be more likely to cause discomfort to the wearer. For this reason, it is preferable that the reinforcing member be a foam sheet. This allows the reinforced region to be provided while minimizing discomfort to the wearer.

[0014] In the above-mentioned innerwear, it is preferable that the rear body portion has an inner layer that is placed on the inside when worn and an outer layer that is placed on the outside when worn, and the rear spacer is attached only to the outer layer, thereby making it possible to prevent unevenness or stiffness caused by the attachment of the rear spacer from being transmitted to the wearer's back and to make the wearer feel less uncomfortable.

[0015] In the above-mentioned innerwear, it is preferable that the rear body portion is formed from a stretch mesh fabric, which allows the innerwear to fit the wearer's body more easily (i.e., the rear spacer can move less relative to the wearer's body), and reduces discomfort to the wearer.

[0016] The innerwear preferably has a front spacer on the front body to ensure space between the wearer's chest and the air-conditioning garment, which makes it possible to prevent airflow on the front side as well as the back side of the wearer's body from being obstructed when a full harness-type fall arrest device is attached to the outside of the air-conditioning garment. [Effects of the Invention]

[0017] As described above, the present invention not only ensures space between the wearer's back and the air-conditioning clothing even when a full-body harness-type fall arrest device is attached to the outside of the air-conditioning clothing, but also makes it possible to provide innerwear for the air-conditioning clothing that is less likely to cause discomfort to the wearer.

[0019] A preferred embodiment of the present invention will be described in more detail with reference to the drawings. In this specification, for convenience of explanation, when the innerwear 1 is worn by a wearer, the upper side as viewed from the wearer will be referred to as "upper," the lower side as "lower," the left side as "left," the right side as "right," the front side as "front," and the rear side as "rear."

[0020] 1. First embodiment FIG. 1 is a back view of the innerwear 1 of the first embodiment. FIG. 2 is a front view of the innerwear 1 of the first embodiment. FIG. 3 is a diagram showing the innerwear 1 of the first embodiment worn inside an air-conditioning garment 2. FIG. 4 is a cross-sectional view of the back body 20 of the innerwear 1 of the first embodiment, taken along plane AA in FIG. 1. FIG. 5 is a cross-sectional view of the front body 10 of the innerwear 1 of the first embodiment, taken along plane BB in FIG. 2. FIG. 6 is an exploded view of the back body 20 of the innerwear 1 of FIG. 1. For convenience of illustration, some of the parts constituting the back body 20 (for example, piping 25, which will be described later) and some of the seam allowances have been omitted from FIG. 6.

[0021] As shown in FIGS. 1 and 2 , the innerwear 1 of the first embodiment includes a front body 10 for covering the chest of the wearer and a back body 20 for covering the back of the wearer. A pair of left and right rear spacers 21a, 21b are provided spaced apart from each other in an approximately left-right middle portion of the back body 20. The rear spacers 21a, 21b in the first embodiment are composed of a left rear spacer 21a that is disposed on the left side as seen from the wearer when the innerwear is worn, and a right rear spacer 21b that is disposed on the right side. The left rear spacer 21a and the right rear spacer 21b are each formed in a rod shape extending in the vertical direction, and the gap between the pair of left and right rear spacers 21a, 21b forms an air flow path 22 for passing air in the vertical direction.

[0022] 3, when this innerwear 1 is worn inside an air-conditioning garment 2 equipped with a fan 2a, the rear spacers 21a and 21b ensure space between the wearer's back and the air-conditioning garment 2. As a result, even when a full harness-type fall arrest device is attached to the outside of the air-conditioning garment 2, the air flow inside the air-conditioning garment 2 is less likely to be impeded, and the cooling function of the air-conditioning garment 2 can be maintained.

[0023] A similar function is believed to be achieved by the air-blower-equipped garment (air-conditioned garment) described in Patent Document 2. However, because the shape and size of the wearer's back vary from person to person, providing an inner pad on the air-blower-equipped garment (air-conditioned garment) side may result in the inner pad not fitting well to the wearer's back or moving relative to the back, causing discomfort to the wearer. In this regard, providing rear spacers 21a, 21b on the innerwear 1 side, as in the innerwear 1 of the first embodiment, makes it easier for the rear spacers 21a, 21b to fit the wearer's back. Furthermore, compared to providing the rear spacers on the air-conditioned garment 2 side, it is also possible to make the rear spacers 21a, 21b less likely to move relative to the wearer's back. This reduces discomfort to the wearer.

[0024] The air flow path 22 formed in the gap between the pair of left and right rear spacers 21a, 21b is designed to overlap the area around the spine, which is a part of the human body that is particularly prone to sweating. When the fan 2a of the air-conditioning garment 2 is driven, air taken in by the fan 2a passes through the air flow path 22 and is discharged from the collar of the air-conditioning garment 2, as shown by the thick arrow in Figure 3. This allows sweat around the spine to be efficiently vaporized, effectively cooling the wearer's body.

[0025] Although the innerwear 1 may have sleeves, the innerwear 1 of the first embodiment is a vest-type garment without sleeves, as shown in FIGS. 1 and 2. The front body section 10 of the first embodiment is made up of a left front body section 10a for covering the left side of the wearer's chest and a right front body section 10b for covering the right side of the wearer's chest, and is an open-front garment that allows the left front body section 10a and the right front body section 10b to be opened. The right end of the left front body section 10a and the left end of the right front body section 10b can be detachably fastened together by fastening means 10c. This allows the innerwear 1 to be easily put on and taken off.

[0026] It is preferable to use a fastening means 10c that allows adjustment of the distance between the left front body portion 10a and the right front body portion 10b (when the right end of the left front body portion 10a and the left end of the right front body portion 10b are to overlap, the degree of overlap). This allows adjustment of the width of the innerwear 1, making it easier to fit the innerwear 1 to the wearer's body. When the innerwear 1 is fitted to the wearer's body, the rear body portion 20 is tensioned and the pair of left and right rear spacers 21a, 21b are firmly separated, making it easier to firmly form the air flow path 22 described above. For example, a buckle (such as a side release buckle or a front release buckle) can be used as the fastening means 10c.

[0027] In the innerwear 1 of the first embodiment, the back body 20 and the front body 10 are formed of a stretch mesh fabric that is breathable and stretchable. This makes it easier to make the back body 20 and the front body 10 fit the wearer's body better and makes it easier to keep the back body 20 in a taut state. This also makes the innerwear 1 more comfortable to wear.

[0028] Stretch mesh fabrics are typically made by combining polyurethane with other fibers. The other fibers may be synthetic fibers, recycled fibers, or natural fibers, either singly or in combination. Synthetic fibers are preferred. Examples of synthetic fibers include polyester, polyurethane, nylon, and acrylic. In the first embodiment, a stretch mesh fabric made of polyester and polyurethane is used.

[0029] The amount of polyurethane contained in the stretch mesh fabric is not limited, but if it is too low, it may be difficult to improve the stretchability of the stretch mesh fabric, and if it is too high, the stretch mesh fabric may be prone to wear. Therefore, the polyurethane content in the stretch mesh fabric is preferably 5% or more, and more preferably 10% or more. Furthermore, the polyurethane content in the stretch mesh fabric is preferably 30% or less, and more preferably 20% or less. In the first embodiment, a stretch mesh fabric (power net fabric) with a polyester content of 86% and a polyurethane content of 14% is used.

[0030] In the innerwear 1 of the first embodiment, as shown in FIG. 1, the upper ends of a pair of left and right rear spacers 21a, 21b are arranged near the neckline 20a of the back body 20. Specifically, the distance W1 from the neckline 20a of the back body 20 to the upper edges of the rear spacers 21a, 21b is 5 cm or less. This ensures a space between the wearer's neck and the collar of the air-conditioning garment 2 (FIG. 3), making it easier for air inside the air-conditioning garment 2 to be smoothly discharged from the collar of the air-conditioning garment 2. The distance W1 is preferably 3 cm or less. There is no particular lower limit to the distance W1, as long as it is 0 cm or more.

[0031] The pair of left and right rear spacers 21a, 21b can be provided on the outside of the back body 20 (the side that will be the outer surface when worn) or on the inside of the back body 20 (the side that will be the inner surface when worn). In the innerwear 1 of the first embodiment, as shown in FIG. 4, the pair of left and right rear spacers 21a, 21b are provided on the outside of the back body 20. In other words, the pair of left and right rear spacers 21a, 21b protrude rearward (rearward as seen from the wearer) from the back body 20. This allows the rear spacers 21a, 21b to be attached to the back body 20 in a manner that is less likely to create unevenness on the inside of the back body 20, making it less likely that the wearer will feel uncomfortable.

[0032] When the rear left spacer 21a is formed in a rod shape, its cross-sectional shape is not particularly limited. However, if the area of the front side surface (the surface facing the wearer's back) of the rear left spacer 21a is smaller than the area of the rear side surface (the surface facing the inner surface of the air-conditioning garment 2), the rear left spacer 21a may be prone to wobbling (rolling) against the wearer's back, which may cause discomfort to the wearer. For this reason, it is preferable that the area of the front side surface of the rear left spacer 21a be larger than the area of the rear side surface. This makes it easier for the rear left spacer 21a to be stable against the wearer's back. The area of the front side surface of the rear left spacer 21a is preferably 1.2 times or more, and more preferably 1.5 times or more, the area of the rear side surface. In the first embodiment, as shown in FIG. 4, the cross section of the rear left spacer 21a is formed into a substantially trapezoidal shape, and the area of the front side surface of the rear left spacer 21a is approximately 1.8 to 1.9 times the area of the rear side surface. A similar configuration can be adopted for the rear right spacer 21b.

[0033] The height H1 of the rear left spacer 21a (i.e., the width in the front-to-rear direction; see FIG. 4) is also not limited. However, if the height H1 of the rear left spacer 21a is too small, it may be difficult to ensure sufficient space between the wearer's back and the air-conditioning garment 2. For this reason, the height H1 of the rear left spacer 21a is preferably 1.5 cm or more, and more preferably 26 cm or more. However, if the height H1 of the rear left spacer 21a is too large, the rear left spacer 21a may become bulky and may be more likely to cause discomfort to the wearer. For this reason, the height H1 of the rear left spacer 21a is preferably 5 cm or less, and more preferably 4 cm or less. A similar configuration can be adopted for the height H2 (width in the front-to-rear direction) of the rear right spacer 21b.

[0034] The rear spacers 21a, 21b (rear left spacer 21a and rear right spacer 21b) are not limited to any particular material. However, if the rear spacers 21a, 21b are too heavy, they may be uncomfortable for the wearer. For this reason, it is preferable to form the rear spacers 21a, 21b from a foam. This allows the rear spacers 21a, 21b to be lightweight. While closed-cell, semi-open-cell, and open-cell foams are known, it is preferable to use closed-cell foam as the foam forming the rear spacers 21a, 21b. This makes it possible to make the rear spacers 21a, 21b less likely to be crushed, even when pressure is applied due to tightening of a full harness-type fall arrest device, for example.

[0035] Closed-cell foam is usually air-impermeable. Therefore, the rear spacers 21a and 21b in the first embodiment are air-impermeable. This makes it possible to prevent air flowing through the air flow path 22 (FIG. 3) formed between the pair of left and right rear spacers 21a and 21b from leaking out to the sides of the air flow path 22, thereby creating a solid air flow near the spine of the wearer.

[0036] The foam forming the rear spacers 21a, 21b is preferably elastic. This reduces the discomfort felt by the wearer. Elastic foams are available in various hardnesses. If the foam forming the rear spacers 21a, 21b is too soft, the rear spacers 21a, 21b may be more easily crushed by tightening of the full harness-type fall arrest device. For this reason, the hardness (hereinafter sometimes simply referred to as "Type C hardness") of the foam forming the rear spacers 21a, 21b, measured in accordance with JIS K7312 (Annex 2) using a Type C durometer (Asker rubber hardness tester Type C) at a temperature of 23±2°C and a relative humidity of 50±5%, by reading the scale 5 seconds after the pressure surface is brought into close contact, is preferably 20 or more. The Type C hardness of the foam forming the rear spacers 21a, 21b is more preferably 30 or more, and even more preferably 40 or more. However, if the foam forming the rear spacers 21a, 21b is too hard, it may cause discomfort or pain to the wearer. For this reason, the Type C hardness of the foam forming the rear spacers 21a, 21b is preferably 80 or less, and more preferably 70 or less.

[0037] The foam forming the rear spacers 21a, 21b can be made of rubber or resin. Specifically, for example, ethylene vinyl acetate copolymer (EVA) foam, chloroprene rubber foam, ethylene propylene rubber (EPDM or EPM) foam, polyurethane foam, silicone rubber foam, natural rubber foam, butyl rubber foam, polyethylene foam, polypropylene foam, polyvinyl chloride foam, etc. In the first embodiment, the rear spacers 21a, 21b are made of EVA foam.

[0038] In the innerwear 1 of the first embodiment, as shown in FIG. 4 , the back body 20 includes an inner layer 23 that is placed on the inside when worn and an outer layer 24 that is placed on the outside when worn. The inner layer 23 and the outer layer 24 are sewn together at their peripheries by piping 25, and the inner layer 23 and the outer layer 24 are otherwise independent of each other (allowing them to move freely relative to each other). The pair of left and right rear spacers 21a, 21b are attached only to the outer layer 24. This prevents unevenness caused by the pair of left and right rear spacers 21a, 21b from being transmitted to the inner layer 23, which is located closer to the wearer's back, making it less likely for the wearer to feel uncomfortable. Furthermore, as described above, when the back body 20 is made of a stretch mesh fabric, the inner layer 23 can stretch independently of the outer layer 24, allowing the back body 20 to fit the wearer's back more easily.

[0039] In the innerwear 1 of the first embodiment, as shown by the dashed polka dot pattern in FIGS. 1 to 3, 5, and 6, the back body 20 is provided with a reinforced region 26 reinforced by a reinforcing member 26a (FIG. 4). The reinforced region 26 is less prone to bending or wrinkling than other portions of the back body 20. As shown in FIG. 4, the pair of left and right rear spacers 21a, 21b are each provided to overlap the reinforced region 26. This prevents the pair of left and right rear spacers 21a, 21b from approaching each other even when a full harness-type fall arrest device is worn on the outside of the air-conditioning garment 2 and is tightened by the full harness-type fall arrest device, making it less likely that the wearer's back will be pinched between the pair of left and right rear spacers 21a, 21b. This also makes it less likely that the air flow path 22 formed between the pair of left and right rear spacers 21a, 21b will collapse.

[0040] The area of the rear body 20 where the reinforcement region 26 is provided is not limited as long as it overlaps at least a portion of the pair of left and right rear spacers 21a, 21b. In the first embodiment, as shown in FIG. 1, the left rear spacer 21a and the right rear spacer 21b are each formed as a rod extending in the vertical direction. When a full harness-type fall arrest device is worn, the upper end portions of the rear spacers 21a, 21b are most likely to be tightened. For this reason, it is preferable that the reinforcement region 26 be provided so as to overlap at least the upper end portions of the pair of left and right rear spacers 21a, 21b. In the first embodiment, as shown in FIG. 6, the reinforcement region 26 is provided in the shape of a vertically elongated strip in the approximately middle portion of the back body 20 in the horizontal direction, so that the reinforcement region 26 overlaps approximately the entire pair of left and right rear spacers 21a, 21b. This makes it more difficult for the pair of left and right rear spacers 21a, 21b to approach each other.

[0041] In the first embodiment, as shown in Figures 1 and 2, a reinforced region 26 is also provided in the back body 20 at a position that overlaps the wearer's shoulders (shoulder portion). The shoulder portion is where the shoulder belt overlaps when the full harness-type fall arrest device is worn, and by providing the reinforced region 26 in this shoulder portion as well, the wearer's shoulders can be protected from tightening by the shoulder belt, etc. The reinforced region 26 in the approximate middle portion in the left-right direction of the back body 20 and the reinforced region 26 in the shoulder portion may be separate, but in this embodiment they are connected.

[0042] The material of the reinforcing member 26a is not limited to a specific one. However, if the reinforcing member 26a is too heavy or too hard, it may cause discomfort to the wearer. For this reason, it is preferable to use a foam sheet as the reinforcing member 26a. Because a foam sheet has flexibility and cushioning properties, using it as the reinforcing member 26a can reduce the discomfort to the wearer.

[0043] The foam sheet can be any of open-cell, semi-open-cell, and closed-cell types. However, in the first embodiment, as described above, the reinforced region 26 (reinforcing member 26a) is provided in the approximately left-right middle portion of the back body 20, from the neckline 20a to the hem 20b. If the breathability of this portion of the back body 20 is poor, it may be difficult for air to reach sweat around the wearer's spine, making it difficult to enhance the cooling function of the air-conditioning garment 2. For this reason, it is preferable to use an open-cell or semi-open-cell foam sheet as the reinforcing member 26a, and it is more preferable to use an open-cell foam sheet. This improves the breathability of the reinforcing member 26a.

[0044] In the first embodiment, as shown in FIG. 4, a perforated foam sheet having a large number of through holes 26a1 is used as the foam sheet. This allows for increased breathability of the foam sheet. The size of the through holes 26a1 is not limited, but if the through holes 26a1 are too small, it may be difficult to increase the breathability of the reinforcing member 26a, and if they are too large, it may be difficult to increase the reinforcing function of the reinforcing member 26a. Therefore, the diameter of the through holes 26a1 is preferably 5 mm or more, more preferably 7 mm or more. The diameter of the through holes 26a1 is preferably 15 mm or less, more preferably 10 mm or less. The proportion of the perforated foam sheet occupied by the through holes 26a1 is preferably 10% or more, more preferably 20% or more. The proportion of the perforated foam sheet occupied by the through holes 26a1 is preferably 50% or less, more preferably 40% or less.

[0045] The thickness of the foam sheet varies depending on the material of the foam sheet and is not limited, but if it is too thin, it may be difficult to obtain a reinforcing effect, and if it is too thick, it may be likely to cause discomfort to the wearer. Therefore, the thickness of the foam sheet is preferably 3 mm or more, and more preferably 5 mm or more. Furthermore, the thickness of the foam sheet is preferably 10 mm or less, and more preferably 7 mm or less.

[0046] The foam sheet is usually made of a rubber or resin foam. Examples of foam sheets that can be used include polyurethane foam sheets, chloroprene rubber foam sheets, ethylene propylene rubber (EPDM or EPM) foam sheets, silicone rubber foam sheets, natural rubber foam sheets, butyl rubber foam sheets, polyethylene foam sheets, polypropylene foam sheets, and polyvinyl chloride foam sheets. In the first embodiment, a polyurethane foam sheet is used as the reinforcing member 26a.

[0047] The reinforcing member 26a (foam sheet) can be directly attached or sewn to the back body 20. However, in this case, the reinforcing member 26a may be prone to breakage or detachment. For this reason, in the first embodiment, as shown in FIG. 4, the reinforcing region 26 is formed using a reinforcing fabric 26c in which protective sheets 26b are attached to the front and back surfaces of the reinforcing member 26a (foam sheet). More specifically, as shown in FIG. 6, the outer layer 24 of the back body 20 is formed by joining the reinforcing fabric 26c with a stretch mesh fabric. This allows the reinforcing member 26a to be attached to the back body 20 in a state where it is less likely to break or detach. The protective sheets 26b used for the reinforcing fabric 26c (attached to the front and back surfaces of the reinforcing member 26a) are preferably thin fabrics that are breathable and stretchable. In the first embodiment, the protective sheet 26b is made of a fabric similar to the stretch mesh fabric that forms the portion of the back body 20 other than the reinforced region 26.

[0048] In the first embodiment, as shown in FIG. 6, the reinforcing fabric 26c that forms the reinforcing region 26 in the approximately left-right middle portion of the back body 20 and the reinforcing fabric 26c that forms the reinforcing region 26 in the left and right shoulder portions are cut separately and joined together, but the reinforcing region 26 in the approximately left-right middle portion and the reinforcing region 26 in the left and right shoulder portions may also be formed from a single continuous piece of reinforcing fabric 26c.

[0049] The method for attaching the rear spacers 21a, 21b to the back body 20 is not particularly limited. For example, the rear spacers 21a, 21b can be glued to the back body 20. However, in this case, the rear spacers 21a, 21b may easily fall off from the back body 20, for example, after repeated washing. Furthermore, the breathability of the portion of the back body 20 where the rear spacers 21a, 21b are glued may be reduced. For this reason, in the first embodiment, as shown in FIG. 4 , each of the pair of left and right rear spacers 21a, 21b (respectively the rear left spacer 21a and the rear right spacer 21b) is wrapped in spacer attachment cloth 27, and the spacer attachment cloth 27 is sewn to the back body 20 (reinforcing fabric 26c therein), thereby attaching the rear spacers 21a, 21b to the back body 20. This makes it possible to prevent the rear spacers 21a, 21b from falling off from the back body 20, even after repeated washing. It also makes it possible to prevent a decrease in breathability of the portion of the back body 20 to which the rear spacers 21a, 21b are attached. There are no restrictions on the type of fabric used as the spacer attachment fabric 27. In the first embodiment, the spacer attachment fabric 27 is made of the same fabric as the stretch mesh fabric that forms the portion of the back body 20 other than the reinforced region 26.

[0050] In the innerwear 1 of the first embodiment, as shown in FIG. 2, front spacers 11a, 11b, 11c, and 11d are provided on the front body 10. This ensures space not only between the wearer's back and the air-conditioning garment 2, but also between the wearer's chest and the air-conditioning garment 2, making it easier to enhance the cooling function of the air-conditioning garment 2. The number and arrangement of the front spacers 11a, 11b, 11c, and 11d are not limited as long as they are arranged in a position that overlaps the wearer's chest when worn. The front spacers 11a, 11b, 11c, and 11d in the first embodiment include a front upper-left spacer 11a arranged at the upper left when viewed from the wearer, a front upper-right spacer 11b arranged at the upper right, a front lower-left spacer 11c arranged at the lower left, and a front lower-right spacer 11d arranged at the lower right. By providing three front spacers 11a, 11b, 11c, and 11d on the top, bottom, left, and right, it is possible to cover a wide area of the wearer's chest while making it easier for the front spacers 11a, 11b, 11c, and 11d to conform to the contours of the wearer's chest.

[0051] As shown in FIG. 2, each of the front spacers 11a, 11b, 11c, and 11d has a block shape, and as shown in FIG. 5, its cross section is generally trapezoidal. This allows the front spacers 11a, 11b, 11c, and 11d to be more easily stabilized relative to the wearer's chest. Furthermore, when the innerwear 1 is viewed from the front (from the negative side in the y-axis direction), the front spacers 11a, 11b, 11c, and 11d are less conspicuous, thereby giving the innerwear 1 a stylish appearance. The front spacers 11a, 11b, 11c, and 11d are provided on the outer side of the front body 10 (the side that faces outward when worn), and the front spacers 11a, 11b, 11c, and 11d protrude forward (forward as viewed from the wearer) from the front body 10. The reason for this is the same as the reason for providing the rear spacers 21a and 21b (FIG. 4) on the outer side of the back body 20.

[0052] The front spacers 11a, 11b, 11c, and 11d are typically made of closed-cell foam. The foam may have the same structure as that of the rear spacers 21a and 21b. The front spacers 11a, 11b, 11c, and 11d and the rear spacers 21a and 21b may be made of different types of foam or the same type of foam.

[0053] As shown in Figure 5, the front body 10 in the first embodiment has an inner layer 12 that is placed on the inside when worn, and an outer layer 13 that is placed on the outside when worn. The inner layer 12 and the outer layer 13 are sewn together at their peripheries with piping 14, and in other areas the inner layer 12 and the outer layer 13 are independent of each other (can move freely relative to each other). The front spacers 11a, 11b, 11c, and 11d are attached only to the outer layer 13. The reason for configuring the front body 10 in this manner is the same as the reason for using a multi-layer structure for the back body 20.

[0054] 5, the front spacers 11a, 11b, 11c, and 11d are attached to the front body 10 by wrapping the front spacers 11a, 11b, 11c, and 11d in spacer attachment cloth 15 and sewing the spacer attachment cloth 15 to the front body 10. This makes it difficult for the front spacers 11a, 11b, 11c, and 11d to fall off from the front body 10.

[0055] 2. Second embodiment Fig. 7 is a back view of the innerwear 1 of the second embodiment. In the innerwear 1 of the first embodiment, as shown in Fig. 1, the reinforced region 26 is provided in the portion from the neckline 20a to the hem 20b in the approximately left-right middle portion of the back body 20 and in the shoulder portions, so that the reinforced region 26 overlaps approximately the entire pair of left and right rear spacers 21a, 21b. Therefore, the reinforced region 26 overlaps approximately the entire air flow path 22.

[0056] In contrast, in the innerwear 1 of the second embodiment, as shown in FIG. 7, the back body 20 is composed of an upper portion and a lower portion, and the reinforced region 26 is provided only in the upper portion (substantially the entire upper portion is the reinforced region 26). More specifically, only the upper portion of the outer layer 24 (FIG. 4) of the back body 20 is formed from the reinforcing fabric 26c, and the lower portion of the outer layer 24 and the inner layer 23 are formed from a stretch mesh fabric. The upper portions of the pair of left and right rear spacers 21a, 21b overlap the reinforced region 26, while the lower portions of the pair of left and right rear spacers 21a, 21b do not overlap the reinforced region 26. Therefore, the reinforced region 26 overlaps only the upper portion of the air flow channel 22, and does not overlap the lower portion. This makes it easier for the air flowing through the air flow channel 22 to hit the wearer's spine and its surroundings. For the parts not described above, the innerwear 1 of the second embodiment may also employ the same configurations as those described for the innerwear 1 of the first embodiment.
